D) Amphibians do not have an amniotic egg.

Explanation:

Amphibians can live in water and on the land but have to lay their eggs in water due to the fact that they do not have amniotic eggs.

What characterizes amniotic eggs is that they have amnion, a membrane that contains a fluid that keeps the embryo moist and prevents it from drying till it dies. In amphibians water is the one that moist the egg till the embryo is ready to come out.
